One chassis in cluster had to be replaced, and transferred RE from bad chassisto new chassis. Now, new chassis goes to disabled state.
On SRX-3400/3600, and SRX-5600/5800, if you replace the chassis, and move the RE from the old chassis to the new chassis, that node will go into disabled state. The reason for this is when the RE is replaced, the fab0 or fab1 interface will have a MAC address mismatch. You can easily detect this by issuing a "show interface fab0":
Physical interface: fab0, Enabled, Physical link is Down Interface index: 232, SNMP ifIndex: 631, Generation: 580 Link-level type: Ethernet, MTU: 9014, Speed: Unspecified, BPDU Error: None, MA C-REWRITE Error: None, Loopback: Disabled, Source filtering: Disabled, Flow cont rol: Disabled, Minimum links needed: 1, Minimum bandwidth needed: 0 Device flags : Present Running Interface flags: Hardware-Down SNMP-Traps Internal: 0x0 Current address: b0:c6:9a:18:18:21, Hardware address: b0:c6:9a:08:88:21 --- snip ---
